The information below describes a typical prokaryote cell, though many bacteria come in different shapes, and sizes and not all contain some of the
features described. Label the parts of the prokaryote using this information.
1. The cell wall protects the cell and gives it shape. It is the
outermost layer on the image
4.
2. On the inside of the cell wall is the cell membrane. Its job is to
regulate what comes in and out of the cell.
5.
1.
3. The surface of some bacteria cells is covered in pilus, which help
the cell stick to surfaces.
7.
4. Some bacteria can move within their environment by using
structures called flagella, which resemble tails.
8.
5. The watery interior of the cell is called cytoplasm.
2.
6. Throughout the cytoplasm are tiny round structures called
ribosomes. Ribosomes make proteins for the cell.
7. Every prokaryote cell has a circular strand of DNA that floats
within the cytoplasm. DNA contains the instructions for the cell and
controls the cell's activities.
3.
8. Many prokaryote cells have a small circular loop of DNA
called a plasmid. The plasmid is used in sexual reproduction.
